Journal ArticleDOI
FLASH imaging rapid NMR imaging using low flip-angle pulses
TL;DR: A new method for rapid NMR imaging dubbed FLASH ( fast low-a ngle sh ot) imaging is described which allows measuring times of the order of 1 s (64 × 128 pixel resolution) or 6 s (256 × 256 pixels), resulting in about a 100-fold reduction in measuring time without sacrificing spatial resolution.
Journal ArticleDOI
Glycolytic oligodendrocytes maintain myelin and long-term axonal integrity

TL;DR: By in vivo magnetic resonance spectroscopy, brain lactate concentrations in mutants were increased compared with controls, but were detectable only in mice exposed to volatile anaesthetics, which indicates that aerobic glycolysis products derived from oligodendrocytes are rapidly metabolized within white matter tracts.
Journal ArticleDOI
Stress-induced changes in cerebral metabolites, hippocampal volume, and cell proliferation are prevented by antidepressant treatment with tianeptine
Boldizsár Czéh,Thomas Michaelis,Takashi Watanabe,Jens Frahm,G. de Biurrun,M. van Kampen,Alessandro Bartolomucci,Eberhard Fuchs +7 more
TL;DR: The effect of tianeptine, a modified tricyclic antidepressant, in the chronic psychosocial stress model of adult male tree shrews, a model with high validity for research on the pathophysiology of major depression, is investigated.
Journal ArticleDOI
Topography of the human corpus callosum revisited--comprehensive fiber tractography using diffusion tensor magnetic resonance imaging.
Sabine Hofer,Jens Frahm +1 more
TL;DR: DTI-based fiber tractography of healthy human subjects suggests a modification of the widely accepted Witelson scheme and a new classification of vertical CC partitions.
Journal ArticleDOI
1H NMR Chemical shift selective (CHESS) imaging
TL;DR: A chemical shift selective (CHESS) imaging technique which destroys the unwanted signal component by means of a selective 90 degrees excitation pulse and a subsequent magnetic field gradient ('homogeneity spoiling gradient') prior to imaging of the wanted component.
